PAPER BAG.

SPECIFICATION forming part of Letters Patent No. 246,621, datedSeptember 6, 1881. Application filed January 12, 1881. (N0 model.)

To all whom it may concern:

Be it known that I, JAMES W. MALOY, of Somerville, in the county ofMiddlesex and State of Massachusetts, have invented certain Improvementsin Paper Bags, of which the following is a specification.

This invention relates to satchel-bottompaper-bags and it consists inthe improvements in a blank for paper bags and in a bag formed from suchblank, which I will now proceed to describe and claim, reference beingmade to the accompanying drawings, forming part of this specification,in which- Figure 1 represents a plan view of a portion of a web or stripof paper having blanks embodying my invention formed thereon. Figs. 2and 3 represent enlarged plans of two adjacent blanks. Fig. 2 representsa view of the bottom of a bag folded from the blank shown in Fig. 2.Fig. 2 represents atransverse section through said bag; Fig. 2 a similarsection with the sides folded in. Figs. 3, 3 and 3 representcorresponding views of the bag formed from the blank shown in Fig. 3.

In all the figures the same letters and figures of reference indicatesimilar parts.

In the drawings,A and B represent adjacent blanks for paper. bags,formed from a continuous strip of paper by the straight cut 0 and theirregular cut d. The cut 0 is simply a transverse out, from side toside, of the strip of paper from which the blanks are made, and formsthetop ofthebagwhen theblankisfolded, and it need not be further described.The irregular cut (I produces V-shaped projections 0 upon the blank A,alternating with depressions of similar shape,f. At the same time itproduces upon the blank B, V-shaped depressions f, corresponding to theprojections 0, alternating with projections 0, corresponding to thedepressions f. The irregular cut d, besides producing the projections e6, with the corresponding depressions ff, on the blanks A and B, as justdescribed, also makes slight longitudinal cuts a a between theprojections e e on each blank respectively, thus partially separatingsaid projections at their bases and enabling the projections to overlapeach other when the bags are folded, as hereinafter described. The cuts0 and d alternate with each other throughout the length of the strips ofpaper from which the blanks are made, thus producing a continuous seriesof blanks.

The blanks, being thus made, are folded by the following operation,reference being made to the blank A shown in Fig. 2. The sides of thebag 1, 2, 3, and 4 are folded on the dotted lines It, I, m, and s. Theedge 1' of the blank being brought to meet the line 8, and the part 5 ofthe blank made to overlap the side 1 of the blank, the bag may be gummedtogether. By this operation the projections c e 6 care brought into suchrelations to each other that they may be folded over toward each otherlike the flaps of an ordinary letter-envelope, as shown in Fig. 2, theiredges overlapping, and thus, when gummed together, forming the bottom ofthe bag. By a similar operation the blank B may be folded, the bottom ofthe completed bag formed therefrom being shown in Fig. 3.

By forming the bottom of the bags in the manner above described it isobvious that 'all waste of material is avoided, the overlapping beingsimply sufficient to secure the requisite strength when the bag isgummed together. By making the portions 2 and 4 of the blank A widerthan the portions 1 and 3, a bag of oblongshape may be produced; and byincreasing the number of projections e 0 formed on the blanks, andcorrespondingly increasing the number of folds, bags of six, eight, orany desired number of sides may be readily made.

I am aware that it is not new to form blanks for paper bags byalternately severing a strip by straight and irregular cuts, formingrespectively the tops and bottoms of the blanks; but I am not aware thata blank has been formed with partially-separated V-shaped projectionatits lower end adapted to everlap and form envelope folds or flaps.

.Having thus described my invention, what Iv claim is-- 1. Theimprovedblank for paper bags herein described, having one end made by atransverse cut to form the top of a bag and the other end made by anirregular out, producing partiallyseparated V-shaped proj ectious on theblank, adapted to overlap each other when In testimony whereof I havesigned my name folded to form the bottom of the bag, as set to thisspecification in the presence of two sub- 10 forth. scribing witnesses.

2. The improx'ed satchel-bottom paper bag,

5 having its bottom made by overlapping envelope-folds, formed bypartially-separated V- W'itnesses shaped projections upon the blank fromwhich 0. F. BROWN, the bag is formed, as set forth. I H. G. VVADLIN.
